what does the lord of the flies reveal to simon

Simon believes that the pig's head speaks to him. He thinks that it is calling him a silly little boy. The Lord of the Flies tells Simon to run off and play with the others, who think that he is crazy. The Lord of the Flies claims that he is the Beast, and the Beast laughs at the idea that the Beast is something that could be hunted and killed, for he is within every human being and thus can never be defeated or escaped from. Terrified and disoriented by this disturbing vision, Simon falls down and loses consciousness.
